  • Publication number: 20210371307
    Abstract: Disclosed is a method and a system for cleaning water in pools, particularly reducing undesired disinfection-by-products. An electrolytic system includes an electrode arrangement including first and second electrodes, functioning as an anode and a cathode, and an Electronic Control Unit. The ECU controls the process so the potential of the anode is 1.4-2.3 V, more preferably 1.6-2.1 V and most preferably 1.7-1.9 V relative the Reversible Hydrogen Electrode. The system and method may further include the use of a reference electrode to control the potential of the first or second electrode to function as a working electrode and being the anode relative the other one of the first and second electrodes being the cathode and functioning as a counter electrode.
